TSplitter is a component in Delphi that allows you to create a splitter control that can be used to resize two adjacent controls at the same time. Here is an example of how to use TSplitter:
- First, you need to add the TSplitter component to the component palette of your Delphi IDE.
- Next, you can drop the TSplitter component onto your form, and place it between the two controls that you want to be able to resize.
- You can then set the
Align
property of the splitter control toalLeft
,alRight
,alTop
, oralBottom
to determine the direction in which the splitter control will resize the controls.
1 |
Splitter1.Align := alLeft; |
- You can set the
MinSize
andMaxSize
properties of the splitter control to define the minimum and maximum size that the controls on either side of the splitter can be resized to.

Splitter1.MinSize := 50; Splitter1.MaxSize := 200; |
- You can set the
ResizeStyle
property of the splitter control torsUpdate
orrsPattern
to determine how the controls on either side of the splitter will be resized.
1 |
Splitter1.ResizeStyle := rsUpdate; |
- You can use the
OnCanResize
event of the splitter control to determine whether the splitter is allowed to resize the controls or not based on some conditions.

procedure TForm1.Splitter1CanResize(Sender: TObject; var NewSize: Integer; var Accept: Boolean); begin if (NewSize < 100) or (NewSize > 300) then Accept := False; end; |
It’s important to note that, when using the TSplitter component, it’s important to make sure that the controls on either side of the splitter are aligned properly and have their Align
property set correctly. Also, the splitter should be placed between the two controls that you want to be able to resize, and not inside one of them.
Additionally, you can use the OnMoved
event of the TSplitter component to perform an action when the splitter is moved by the user. This can be useful for updating the status of the controls or for performing other tasks.

procedure TForm1.Splitter1Moved(Sender: TObject); begin ShowMessageFmt(‘Splitter moved to %d’, [Splitter1.Left]); end; |
When using the TSplitter component, it’s important to test your application in different screen resolutions and on different platforms to ensure that the splitter works as expected and that the controls are resized correctly.
